1. Dab tsi yog qhov txawv ntawm cov nickel alloys thiab stainless hlau alloys?
Teb:
Nickel Alloys (Inconel, Incoloy, Monel, Hastelloy): Siab - cov ntaub ntawv ua tau zoo tsim los rau kev tiv thaiv corrosion tsis zoo, siab - kub lub zog, thiab qaug zog tiv thaiv. Haum rau tshuaj lom neeg, marine, aerospace, thiab siab - kev siv siab.
Stainless Steels (Alloy 20, Duplex 2205, Super Duplex 2507): Feem ntau yog hlau-raws li chromium, nickel, thiab molybdenum. Lawv muaj kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog rau chlorides, thiab muaj zog ntawm nruab nrab mus rau qhov kub thiab txias. Duplex thiab super duplex steels muaj zog dua thiab zoo dua cov tshuaj chloride kev nyuaj siab -corrosion cracking kuj dua li cov qauv stainless hlau.
2. Cov kev lag luam twg feem ntau siv cov kav hlau alloy no?
Teb:
Cov kav dej no tau siv dav hauv kev lag luam uas xav tau kev tiv thaiv corrosion siab, lub zog, thiab kav ntev:
Chemical & Petrochemical: Reactors, heat exchangers, thiab pipelines tuav cov kua qaub, alkalis, thiab lwm yam tshuaj phem.
Roj & Roj: Cov kav dej tawm ntug dej hiav txwv, cov khoom siv hauv qab hiav txwv, thiab siab - qhov dej siab xav tau kev tiv thaiv dej hiav txwv corrosion thiab kev ntxhov siab.
Fais fab Generation: boilers, turbines, thiab tshav kub exchangers raug kub thiab siab.
Marine & Desalination: Seawater twj, li qub, thiab cov kav dej uas muaj chloride corrosion yog ib qho kev txhawj xeeb.
Khoom noj khoom haus & Pharmaceutical: Cov kav dej uas tswj kev nyiam huv thiab tiv thaiv corrosion los ntawm acidic lossis alkaline xov xwm.
3. Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev siv seamless alloy kav hla welded kav?
Teb:
Lub zog siv tshuab siab dua: Cov kav dej tsis muaj seamless tsis muaj vuam seams, ua rau lawv tiv taus ntau dua rau siab -siab.
Kev tiv thaiv corrosion zoo dua: Tshem tawm cov ntsiab lus tsis muaj zog nyob ib puag ncig welds qhov twg corrosion tuaj yeem pib.
Uniformity: Muab cov phab ntsa tuab zoo ib yam thiab cov khoom siv kho tshuab raws li qhov ntev.
Kev qaug zog ua haujlwm: Kev ua tau zoo tshaj plaws hauv kev thauj khoom cyclic lossis siab -kev siv kub.
Precision thiab kev ntseeg siab: Zoo tagnrho rau cov ntawv thov tseem ceeb hauv kev lag luam aerospace, tshuaj lom neeg, thiab kev lag luam offshore.
4. Yuav ua li cas koj xaiv qhov zoo alloy rau ib daim ntawv thov tshwj xeeb?
Teb:
Kev xaiv nyob ntawm qhov chaw corrosion, kub, mechanical stress, thiab siab xav tau:
Inconel 625 & 718: Siab- kub thiab siab - siv zog, turbines, thiab tshuaj reactors.
Incoloy 800 & 825: Siab -kub oxidation thiab tshuaj tiv thaiv, tshav kub exchangers, thiab tshuaj ua.
Monel 400 & K500: Zoo heev marine thiab seawater tsis kam; K500 ntxiv zog rau cov khoom siv kho tshuab.
Hastelloy C276 & C22: Ua kom muaj zog oxidizing thiab txo cov kua qaub; haum rau tshuaj thiab tshuaj industries.
Alloy 20: Zoo heev tiv taus sulfuric acid thiab tshuaj lom neeg corrosion.
Duplex 2205 & Super Duplex 2507: Siab chloride kev nyuaj siab -corrosion cracking resistance; zoo tagnrho rau seawater, roj, thiab roj industries.
5. Dab tsi yog cov ntawv thov rau cov nickel thiab stainless hlau alloy kav?
Teb:
Kev siv tshuaj: thauj cov kua qaub, alkalis, thiab tshuaj corrosive.
Roj & Roj: Subsea pipelines, risers, siab - cov txheej txheem siab, thiab offshore platforms.
Fais fab nroj tsuag: High-kub kab, boilers, thiab turbine Cheebtsam.
Marine & seawater daim ntaub ntawv: Twj, li qub, desalination systems, thiab tshav kub exchangers.
Khoom noj khoom haus, dej haus, thiab tshuaj lag luam: Corrosion-cov kav dej tiv taus rau cov txheej txheem huv lossis tsis muaj menyuam.
Cov alloys no ua kom ntev - lub sij hawm durability, kev nyab xeeb, thiab kev ua tau zoo nyob rau hauv kev ua hauj lwm huab cua, ua rau lawv haum rau siab -end industrial applications.
